FIRE-ALARM PISTOL.

SPECIFICATION forming' part of Letters Patent No. 718,211, dated January 13, 190.

Application tiled August 18,1902. Serial No. 120,124. (No model.)

Be it known that I, CHARLES E. LOMBARD, a citizen of the United States, residing at East Wilton, in the county of Franklin and State of Maine, have invented certain vnew and useful Improvements in Fire-Alarm Pistols; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it' appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to a fire-alarm pistol, and has for an object to provide a pistol which can be used as an ordinary weapon of defense or as an alarm in case of a 'fire when properly connected with fusible means for operating the trigger thereon upon a dangerous increase in temperature.

Other and further objects and advantages of the invention will be hereinafter set forth, and the novel features thereof defined by the appended claims.

In the drawings, lFigure 1 is a side Yelevation of the invention with parts in section; Fig. 2, a perspective thereof, showing a moditied means for controllingthe trigger-operatinglever; and Fig. 3, a vertical section on line 3 3 of Fig. l.

Like letters of reference refer to like parts in the several figures of the drawings.

The letter A designates the barrel of a pistol, which is provided at one end with a handle A', secured thereto by screws A2, and at the opposite end with a sight A3. dle end of the barrel a breech-clasp A4 is pivoted at A5 and provided with an aperture A6 for the passage of the pin o'f the hammer A7, which is pivoted at A8 in the handle. VThis hammer is formed with a setting-shoulder A9 and spring-socket A10, adapted to receive the end B of the pivoted trigger B and the end of the firing-*spring 0,' respectively. This spring is held at its opposite end in a socket C and passes over a bridge C2, carried by the handle, so as to be placed under compression when the hammer is raised. The extended end B2 of the trigger B is also held under tension by a spring C3, secured at its opposite end C4 to the handle, as shown.

At the han-V A D designates a ring-lever which is pivoted to the casing at one end Dl and supported at its opposite apertured end D2 by an apertured lug D3, carried by the under side of the barrel, over which said end D2 passes, and is held by a catch E, having a fusible pin E', passing through the aperture in the lug D3. This catch is pivotally mounted by having its rod E2 passed through keepers upon lthe lever, and the vertical arm E3 of the catch is provided with opposite connecting-eyes E4, adaptV ed for use when the pistol is used with an extended fusible wire F, as shown in Fig. 2. The Wire thus used is made in sections, which are connected together by a solder fusible at a proper temperature, and at the opposite side of the catch from this' Wire is a tensiom spring F', which acts to throw the catch and permit the lever to operate the trigger when the fusible line is broken by any cause. The flring`- lever I) is also assisted by a coiled spring D5, mounted in a socket D6 and bearing upon the upper face of the lever.

In the operation of the invention the pistol may be placed in any location or position 'where a re is liableV to occur, and any dan' tected, as the line ,may be stretched across an apartment under tension,and when broken by fusing the spring will rotate the catch upon its pivot, thus releasing the lever and firing the pistol to sound the alarm.

It will be obvious that changes may be made in the details of construction and configuration of the several parts and in the character of pistols to which the invention is applied, as well as that of the fusible line, without departing from the spirit of the invention as defined by the appended claims.

Having described my invention and set forth its merits, what I claim, and 'desire to secure by Letters Patent, is'- l. In fire-alarm pistol, the combination with a trigger thereof, of a firing-lever pivoted adjacent thereto, a spring for forcing said lever in contact with ythe trigger a depending lug from the pistol-barrel over which the free end of the lever passes, a pivoted catch mounted IOC upon said lever and adapted to engage said lug, and means for oscillating said catch, substantially as specified.

2. In a fire-alarm pistol, the combination with a trigger thereof, of a firing-lever pivoted adjacent thereto, a spring for forcing said lever in contact with the trigger a depending lug from the pistol-barrel over which the free end of the lever passes, a pivoted catch mounted upon said lever, and adapted to engage said lng, a fusible line connected to one side of said catch, and a tension-spring connected to the opposite side thereof, to osoillate the catch When the line is broken, substantially as specified.

3. In a fire-alarm pistol, the combination with the barrel thereof, of a breech-clasp pivotally mounted thereon, and provided with a firing-aperture, a hammer mounted to coperate with said aperture, and a trigger for releasing said hammer, an angular lever pivotally mounted in advance of said trigger, and provided upon its under face With bearing-lugs, a catch pivotally mounted in said lugs, to operate at a right angle to said lever, a spring for holding the lever under tension, a depending lug from the pistol, adapted to pass through said lever, and provided with an aperture to receive the end of said catch, and connecting-eyes disposed upon the opposite sides of said catch for the purpose of oscillating the same, substantially as specified. v

In testimony whereof I hereunto afiix my signature in presence of tWo Witnesses.

CHARLES E. LOMBARD.
